Lock Lavanini will form part of a teak-tough Pumas pack for the Aviva Stadium encounter, where Ireland will be itching for revenge for their 43-20 loss to Argentina in the 2015 World Cup quarter-final.

Star half-backs Martin Landajo and Nicolas Sanchez will link up for head coach Daniel Hourcade's side, with 24-year-old Lavanini expecting a fierce battle up front.

"We know what kind of team Ireland are," said Lavanini.

"I've played against them three times, and the truth is that they are always a very tough opponent with a very strong and heavy pack. And that's something that we have always struggled to counter-act.

"They have a strong aerial threat in the second row, their front row is extremely technical and neat, and in general they are a very hard team to penetrate.

"Winning our set-piece and then retaining ball will be vital, because with the smallest error they will make you pay," he said.

"The breakdown will also be key because they know how to make the game slow, and that will be fundamental when it comes to attacking them."
